CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority from U.S. Provisional Application No. 61/542,364, entitled SYSTEM, ARCHITECTURE AND METHOD FOR SECURE ENCRYPTION AND DECRYPTION, and filed on Oct. 3, 2011, which is incorporated herein by reference in its entirety.

FIELD OF THE INVENTION

The present disclosure relates to a system, architecture and method for secure encryption and decryption.

BACKGROUND

Today, more than ever, companies face a daunting challenge of establishing secure IT environments to prevent hacking and break-ins. Computing power continues to advance at a rapid rate, and encryption algorithms once thought to be secure are becoming less secure, as hacking tools become more powerful. Recent major security breaches of not just regular companies but also companies in the business of electronic data security themselves have been victims of sophisticated hacking efforts. These incidents have demonstrated the need to continue to develop stronger encryption tools and architectures in order to secure sensitive data from breach. As a result, what is needed is an improved system, architecture and method for encryption and decryption that will make it even more difficult for hackers to gain unauthorized access to sensitive, encrypted data.

SUMMARY

As noted above, the present invention relates to a system, architecture and method for secure encryption and decryption. More particularly, the present system, architecture and method provides an encryption method which generates a user specific encryption key based on analyzing the linguistic attributes or characteristics of clear text in a record to be encrypted.

In an embodiment, the system and method analyzes the linguistic characteristics or attributes of every clear text record and generates a unique Linguistic Encryption Key for every encryption process.

In another embodiment, multiple levels of encryption processes are used in combination, with at least one of the levels encrypted using a unique Linguistic Encryption Key based on an analysis of the record to be encrypted.

The present invention prevents any common and conceivable option to decipher the cipher text because multiple encryption levels and keys generated from random code for every record for every user makes it virtually impossible for deciphering algorithms to find any “common” similarities between different cipher texts.

DETAILED DESCRIPTION

As noted above, the present disclosure relates to a system, architecture and method for secure encryption and decryption. More particularly, the present system, architecture and method provides an encryption method which generates a user specific encryption key based on analyzing the linguistic attributes or characteristics of clear text in a file to be encrypted.

The user specific and file dependent Linguistic Encryption Key is different for each file based on the particular linguistic attributes or characteristics of each record or file, such that the resulting cipher text cannot be analyzed for any patterns as between two records or files encrypted with different Linguistic Encryption Keys. As will be explained in more detail below, even the deletion of a single space from a text in a record results in a completely new cipher text that cannot be compared to the cipher text for the original text having the extra space. Only the specific Linguistic Encryption Key used for encryption of the record may be used to decrypt the record. In an embodiment, the user specific multiple Linguistic Encryption Keys are managed by a central security server which provides secured access based on a device and user authentication procedure, such that only an actual authenticated user may access the Linguistic Encryption Keys.

An illustrative embodiment of the present invention will now be described in detail with reference to FIGS. 1 to 4 as enclosed.

Referring to FIG. 1, shown is a schematic representation of an illustrative system and architecture 100 in accordance with an embodiment. As shown, system 100 includes a security server 102 operatively connected through a firewall 104 to a corporate network 106. Corporate network 106 in turn is operatively connected to a fully encrypted database server 108.

Security server 102 is configured to securely store various user accounts, and encryption keys associated with each user account. Security server 102 does not store clear text, and access is only granted after an authenticated device/user verification process is successful. Firewall 104 is configured to allow access only to a fully encryption database server 108. By having security server 102 disconnected from the Internet and only being authorized to be accessed by the encryption database server 108, hackers cannot gain access to the key reference tables.

Corporate network 106 is operative connected through a firewall 110 to an Internet router gateway 112 connected to the Internet 114. The Internet 114 allows a plurality of devices 116 to access the database server 108 if the device 116 and user are properly authenticated, as described in further detail below. As shown, the devices 116 may include a desktop computer, a laptop computer, a smart phone, a tablet, and the like, which may connect wirelessly or via an Ethernet connection.

Now referring to FIG. 2, shown is a schematic flow diagram of an illustrative authentication method 200 using profiles in accordance with an embodiment.

As shown, the authentication process begins at block 202, where process 202 initiates a logon screen to provide access to an encryption/decryption website via database server 108. Method 200 proceeds to block 204 where the username/password are entered.

In an embodiment, method 200 then proceeds to block 206, where method 200 performs a device identification step which may include, for example, reading a WAN IP address, a MAC address, a browser version, an OS version, and/or a LAN IP address for a device 116 attempting to access the system. The resulting device profile should match the profile of a device already authenticated within a user's profile. By requiring a device authentication step to confirm that the device is one normally used by a registered user to access the system, a first level of security may be provided based on the accessing device. Upon successful login, a unique “user-specified key” is distributed to the device and cross referenced on security server 102.

Alternatively, the system may allow a user to access data from any device available, including devices which have not been preauthorized. This may be the case, for example, where a system is accessed by a user through a given device for the first time, as the device is new and has not yet been authenticated. In this case, the user may be required to answer additional questions or to complete additional verification steps before being authorized to access the system. As soon as the correct answers have been given, the device is authenticated for the future via a stored record or reference uniquely identifying the authenticated device.

At decision block 208, method 200 determines whether the entered profile for a username exists. If no, method 200 proceeds to block 210, where method 200 generates three unique one time pad keys for multiple encryptions. Method 200 then proceeds to block 212, where method 200 automatically generates a new “auto-authenticated” profile for the username/password. Method 200 then proceeds to block 214, where method 200 flags the profile as authenticated, and grants access to record sets associated with the user profile.

At decision block 208, if the answer is yes, method 200 proceeds to decision block 216, where method 200 compares the profile with the device readout for a match. If there is a match, method 200 proceeds to block 214, where method 200 flags the profile as authenticated, and grants access to record sets associated with the user profile.

At block 216, if there is no match, method 200 proceeds to block 218, where method 200 automatically emails a warning to the system administrator. At block 220, method 200 also automatically sends an email to the account holder of the username to alert the account holder of a lack of a match. Method 200 then proceeds to block 222 where method 200 flags the accounts as to be verified.

Method 200 then proceeds to block 224, where method 200 reviews the entry of security answers to a set of non-standardized profile security questions. At block 226, method 200 compares the profile answers with the keyed answers. Method 200 then proceeds to decision block 228, where method 200 determines whether the keyed answers are compliant with the profile set. If yes, method 200 proceeds to block 214, flags the profile as authenticated, and grants access to the record sets associated with the user profile.

At decision block 228, if the answer is no, method 200 proceeds to block 230, where method 200 flags the readout as a suspected hacking attempt and denies access.

Now referring to FIG. 3, shown is a schematic flow diagram illustrating a method of encryption in accordance with an embodiment. As shown, method 300 begins at block 302, where method 300 begins with the creation of a Random Key 1. Method 300 then proceeds to block 304, where method 300 encrypts a target Record X with Random Key 1. Method 300 then proceeds to block 206, where Random Key 1 is stored for Record X for a User Y.

Next, method 300 proceeds to block 308, where method 300 performs an analysis of the linguistic attributes or character of the original clear text within Record X. For example, in an embodiment, one or more of the following linguistic attributes or characteristics may be checked within the clear text:

-   -   1. Length     -   2. Number of spaces     -   3. Number of commas     -   4. Number of Hyphens     -   5. Number of Exclamation Marks     -   6. Number of Words

It will be appreciated that the above linguistic attributes are illustrative, and other types of linguistic attributes of the clear text may be used instead, such as the number of certain characters or punctuations, for example. Any linguistic attributes or characteristics that would provide a sufficiently high degree of randomness and uniqueness for a given piece of clear text may be used to perform an analysis.

Based on this analysis of the linguistic attributes or character of clear text in Record X, method 300 creates a Linguistic Encryption Key. For example, the linguistic attributes may be used to generate a “salt” (i.e. a string of random bits) to create a one-way function which will further encrypt the clear text.

As an illustrative example, a possible Linguistic Encryption Key may look like this:

-   -   a. 130/10?2!0@4&43     -   b. 130=String length     -   c. /=Separator     -   d. 10=number of spaces     -   e. ?=Separator     -   f. 2=number of commas     -   g. !=Separator     -   h. 0=Number of hyphens     -   i. @=Separator     -   j. 4=Number of Exclamation Marks     -   k. &=Separator     -   l. 43=Number of words

The Linguistic Encryption Key as illustrated above is based on a linguistic analysis of each record.

Advantageously, the Linguistic Encryption Key adds a twist to an encryption process in a way that is unpredictable, thus making the encryption much more difficult to break.

Next, method 300 proceeds to block 310, where the salt generated from analysis of the linguistic attributes of a record is used to create a Linguistic Encryption Key, which is then used to encrypt Record X.

Method 300 then proceeds to block 312, where method 300 stores the Linguistic Encryption Key for Record X, for User Y.

Method 300 then proceeds to block 314, where method 300 creates a Random Key 2, and at block 316 further encrypts the encrypted Record X with Random Key 2.

Method 300 then proceeds to block 318, where method 300 stores Key 3 (Random Key 2) for Record X, for User Y.

Method 300 then proceeds to block 320, where method 300 creates a Random Key 3, and at block 322 further encrypts Record X with Random Key 3. At block 324, method 300 stores Key 4 (Random Key 3) for Record X, for User Y. Thus, for every Record X, the unique set of keys are stored and referenced for every User Y.

Still referring to FIG. 3, shown in parallel with method 300 is a schematic representation of Record X, which at 326 is shown to be clear text to be encrypted.

Next, Record X is shown at 328 adjacent block 304 as encrypted text at Level 1 based on clear text encrypted with a Random Key 1.

Next, Record X is shown at 330 adjacent block 310, where Record X is now encrypted at Level 2 using a Linguistic Encryption Key.

Record X is shown again at 332 adjacent block 316, where Record X is now encrypted at Level 3 using Random Key 2.

Finally, Record X is shown again at 334 adjacent block 324, where Record X is now encrypted at Level 4 using Random Key 3.

Thus, to make the encryption stronger and more complicated for potential hackers, multiple levels of locks may be employed, including at least one level involving analysis of linguistic attributes of the record being encrypted to make it virtually impossible for hackers to break the encryption (e.g. by locating the common letters “e” and “a”, and trying to extrapolate the rest of the alphabet).

As shown at 336, decryption of Record X is accomplished by unlocking each level of encryption using the corresponding key in a reverse operation. More particularly, the linguistic encryption key is operable to decrypt the encrypted target record in a reverse operation.

While this illustrative example has shown the Linguistic Encryption Key being used as a second level of encryption in a multi-level encryption process, it will be appreciated that the Linguistic Encryption Key may be used at another level of encryption, such as the first or third. As well, the number of levels of encryption may be varied to be higher or lower than four levels, although the inventors have determined that four levels of encryption including at least one level of encryption using a Linguistic Encryption Key provides a high degree of apparent randomness and security such that the encrypted record is very difficult to break without the keys.

Example 1

An illustrative example of linguistic encryption may be shown using the following sample clear text from a news article, which is converted to cipher text using a Linguistic Encryption Key.

-   -   “(CLEAR TEXT) Cairo (CNN)—Egyptian police trying to clamp down         on demonstrations against President Hosni Mubarak early this         year were told to use tear gas, but not automatic weapons or         live ammunition, a senior Egyptian police official testified         Monday at Mubarak's trial.     -   General Hussein Saeed Mohamed Mursi was one of several senior         police officials due to testify Monday.     -   During his testimony, prosecutors attempted to cast doubt on         Mursi's credibility, as he was in charge of communication         between police forces on the ground.     -   According to testimony, police were ordered to use police         vehicles to disperse protesters, Egyptian state television         reported.

Using the user and profile specific encryption key, and in conjunction with the linguistic encryption algorithm, the following cipher text results:

Comparing this to a slightly modified clear text, taking out just one space before the word “Egyptian” will result in cipher text that contains significant encryption changes that make the cipher text completely unrecognizable when compared to the original cipher text as illustrated by this example.

Due to the generation of an entirely different cipher text based on just a minor difference in the clear text, it will be recognized that the present system, architecture and method provides a powerful way to encrypt clear text making it very difficult, if not impossible, to try to analyze encrypted text based on identifying similarities or patterns in different samples of cipher text. For example, a hacking method of trying to find patterns in the cipher text identifying common vowels such as “a” and “e” is of no use, as the cipher text will vary unrecognizably from one record to the next based on, for example, the removal of a single space from a passage of text.

Example 2

As illustrated by another example using a Chinese phrase, it will be seen that the cipher text resulting from encryption provides just as much apparent randomness in the cipher text as a passage of text in English, once again making it difficult if not impossible to try to analyze the code based on pattern analysis.

For example, the following Chinese language text

becomes:

-   -   sNILDII8mTQbjBBzpTo264Ahosdp/IMwqb         cKDj5FJXxAaEmFxYZzaCyOlsJgQJff7Dky         eW1MmCGqj0f5VXPpyElTh387ESUsgBZ QpmMUcdip62t9RnRYIiIHTLxEBSv4oGV         yKoKuEVjK3NrfSMJ0OWu8qL0cA5V/nNYwNYeaMluz9YPjjoaJAhR9kEvE+UG+seD5Llec0n0u/b2i7h0+e9zcAHROeSm         VQjBWe37KeA82nMo6XIEonXL25BEBm Chs13+gJN+7QFge3oxwtQMzkYYx1SFzeY         NJNAm89CPCdnwuWMmvdiruG/mss7Iwlf 1gm7JRSEPCEg6iIAvg==

In an embodiment, while another character set could have been chosen, the default encryption character set is Latin (i.e. A-Z, 1-9, !@# . . . ) such that the cipher text appears to be a random sequence of Latin characters. Decryption occurs in whichever language the clear text might be in.

In an embodiment, every character is selected for encryption is represented internally in the system as a hexadecimal number. Non-Latin character sets such as Chinese and Russian may use the standard international UTF-8 code system which covers virtually all character sets in existence, and also allows any characters in the character sets to be based on those internal hex codes.

Example 3

As yet another example, the present system. method and architecture may be used to convert the following Russian text
